Biodegradable technology is established technology with some applications in product packaging, production, and medicine. [31] The chief barrier to widespread implementation is the trade-off between biodegradability and performance. For example, lactide-based plastics are inferior packaging properties in comparison to traditional materials.

Almost all plastic is non-biodegradable and without recycling, spreads across the environment [109] [110] where it causes plastic pollution. For example, as of 2015, approximately 8 million tonnes of waste plastic enters the oceans annually, damaging oceanic ecosystems and forming ocean garbage patches. [111]
A plastic is considered biodegradable if it can degrade into water, carbon dioxide, and biomass in a given time frame (dependent on different standards). Thus, the terms are not synonymous. Not all bioplastics are biodegradable. [44] An example of a non-biodegradable bioplastic is bio-based PET. PET is a petrochemical plastic, derived from ...
Almost all plastic is non-biodegradable and without recycling, spreads across the environment [8] [9] where it causes plastic pollution.

Biodegradable waste can be used for composting or a resource for heat, electricity and fuel by means of incineration or anaerobic digestion. [7] Swiss Kompogas and the Danish AIKAN process are examples of anaerobic digestion of biodegradable waste.
PET is considered to be essentially non-biodegradable, with plastic bottles estimated to take as long as 450 years to decompose. [8] Because of this, other packaging materials are being sought. Calcium alginate gel
Some examples of mixed waste in this context include a combination of broken glassware, floor sweepings, non-repairable household goods, non-recyclable plastic and metal, clothing, and furnishings. Additionally, ashes, soot, and residential renovation waste materials are also included under this definition.
